Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.

About this study

The investigators' proposed study is a randomized controlled trial that will prospectively examine the effect of a multicomponent intervention on the rate of hospitalizations, daily physical activity, self efficacy and health status in patients who have COPD and have been hospitalized because of a COPD exacerbation.

In the study, a convenience sample of patients recently hospitalized for a COPD exacerbation, who meet the selection criteria and agree to participate will be randomized to receive one of the following at the time of hospital discharge: (1) the current standard of care plus a multicomponent intervention (counselor + pulmonary rehabilitation) or (2) the current standard of care without the intervention.

This study plans to test the following hypotheses: (1) The primary outcome of the study to be the composite endpoint of death or COPD hospitalization (2) Time to first rehospitalization will be shorter in the intervention group than the control group (3) At follow-up, the physical activity level measured in terms of the average number of steps and active energy expenditure will be higher in the intervention group than in the control group.

Study phase:

During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study

This phase I clinical trial investigates the side effects and the best dose of local (intrapleural measles virus therapy in treating patients with malignant pleural mesothelioma (MPM). The investigators anticipate that the intrapleural of the vaccine strain measles virus will enable the virus to specifically infect and kill cancer cells and spare, without damaging normal cells. Furthermore, the investigators expect the measles virus to trigger an anti-tumor immune response which will result in additional destruction of the tumor by immune cells.

About this study

The purpose of this research is to study a medical device that is designed to produce lung volume reduction. This device is called the PulmonX Endobronchial Valve (EBV). It has not been approved by the Food and Drug Administration (FDA) and is considered investigational. The EBV is a one-way valve that blocks off the diseased lung section to inhaled air but lets the trapped air already inside the area escape. With placement of the EBV, the diseased part of the lung collapses which allows the healthier parts of the lung to expand.

The EBV can be placed by a doctor in a diseased section of the lungs using bronchoscopy. Bronchoscopy is a way to access the lungs using a small tube with a camera on the end. With bronchoscopy, a physician can reach the airways in the lung by passing the tube through either the mouth or nose. Use of bronchoscopy for performing lung volume reduction may have fewer risks than surgery and have reduced recovery time.

This study is designed to investigate the safety and effectiveness of the Pulmonx EBV for treating emphysema symptoms as compared to a standard medical therapy program alone. It is hypothesized that after placement of the EBV, lung function will be improved as compared to standard medical therapy alone.

About this study

This is a multi-center, randomized, placebo-controlled, double-blind, parallel group trial evaluating mepolizumab 100 mg against placebo given every 4 weeks through subcutaneous (SC) injection.

In severe COPD patients, sputum eosinophils levels are elevated similar as those seen in severe asthmatics. It is hypothesized that the reduction of eosinophils with mepolizumab in COPD patients would translate into a reduction of COPD exacerbations. The study will determine the reduction in exacerbations in subjects who are above and below the baseline blood eosinophil count of at least 150 cells/microlitres. The study will evaluate the efficacy and safety of mepolizumab on the frequency of moderate and severe exacerbations in COPD subjects at high risk of exacerbations, despite the use of optimized standard of care background therapy.

Overall in this study, a total of 800 subjects will be randomised in 1:1 ratio to receive placebo or mepolizumab (100 milligram (mg)) administered SC. The total duration of this study will be approximately 62 weeks, consisting of a 1 to 2 week screening period, 52-week treatment period and 8-week follow-up period.

About this study

The main purpose of this clinical trial is to determine the safety and effects of the study drug, sorafenib, in adults diagnosed with hepatopulmonary syndrome (HPS). The study will evaluate how well the drug is tolerated and its effect on the level of oxygen in the blood and the function of the lung vessels.

About this study

The goal of this project is to determine if the change in oxygen saturation during deep inspiration ("augmented pulse oximetry") can be used as a method to rule out pulmonary embolism (PE). The investigators propose to evaluate a simple, non-invasive clinical tool to help rule out PE. The investigators plan to measure the oxygen saturation of 40 consecutive patients with newly-diagnosed PE (within 60 minutes of diagnosis) and 80 matched controls who do not have a PE. Trained, blinded Respiratory Therapists will record each patient's oxygen saturation before, during, and after a 2-minute period of deep inspirations (vital capacity [the maximal amount of air that can be inhaled, measured in milliliters]) using an incentive spirometer. The investigators' central hypothesis is that persons with a PE will not respond to augmented pulse oximetry and will not significantly improve or normalize their oxygen saturation.
